DESCRIPTION
DESCRIPTION
FireHawk M7 Air Masks from MSA are pressure-demand,
self-contained breathing apparatus (SCBA) certified by the
National Institute for Occupational Safety and Health
(NIOSH) for use in atmospheres immediately dangerous to
life or health:
``Immediately dangerous to life or health’’ means condi-
tions that pose an immediate threat to life or health or
conditions that pose an immediate threat of severe expo-
sure to contaminants, such as radioactive materials,
which are likely to have adverse cumulative or delayed
effects on health [Title 42 CFR, Part 84.2, (Q)].
This Air Mask complies with the National Fire Protection
Association (NFPA) Standard 1981 for Open-Circuit Self-
Contained Breathing Apparatus for Fire Fighters
This Air Mask has been designated by NIOSH as being
CBRN (chemical, biological, radiological, and nuclear)
Agent Approved. It complies with the special tests under
NIOSH 42 CFR 84.63(c); Chemical Agent Permeation and
Penetration Resistance Against Distilled Sulfur Mustard
(HD) and Sarin (GB) and the Laboratory Respirator
Protection Level (LRPL) tests.

FIREHAWK M7 AIR MASK COMPONENTS
PR14 FIRST STAGE REGULATOR
The PR14 First Stage Regulator reduces the pressure
from the cylinder and valve assembly to an intermediate
pressure, which is in turn further reduced by the Firehawk
Second Stage Regulator to a pressure that is respirable
by the user.
The PR14 First Stage Regulator incorporates a down-
stream design and dual springs.
The regulator incorporates a large, easily replaceable, sin-
tered filter to capture particulates that may be in the air
stream.
FIREHAWK SECOND STAGE REGULATOR
The Firehawk Regulator is a pressure-demand regulator,
which maintains a positive pressure in the facepiece while
the air mask is in use.
The Firehawk Regulator attaches to the facepiece via a
slide-to-connect or a push-to-connect feature.
The Firehawk Regulator has two available covers, purge
and hard cover. The purge cover offers the user the ability
to manually activate the regulator or to provide a quick
burst of air during use without using the bypass knob.
There are also two types of Firehawk Regulator intermedi-
ate pressure hose connections, threaded and quick-con-
nect.
CYLINDER AND VALVE ASSEMBLY
*as approved by NIOSH
The cylinder valve includes a metal valve body, threaded
connection for filling and attachment of the Audi-Larm
Alarm, handwheel, safety disc (burst disc), and pressure
gauge.
The pressure gauge continuously shows the air pressure
in the cylinder.
The handwheel is used to open and close the cylinder
valve.

AUDI-LARM ALARM WITH URC ASSEMBLY
The Audi-Larm Alarm rings when there is approximately
25% of the air mask’s rated service time remaining and
when the cylinder valve is first opened, providing an audi-
ble indication that the alarm is working properly.
A high pressure hose delivers air at cylinder pressure from
the Audi-Larm Alarm to the PR14 First Stage Regulator.
Note: The remaining service time calculations are based
on a 40 LPM (liters per minute) NIOSH breathing rate.
All FireHawk M7 Air Masks are equipped with an Audi-
Larm Alarm that includes a URC Assembly (Universal
Rescue Connection). The URC Assembly is a male quick-
fill inlet for use by Rapid Intervention Crews for emer-
gency filling of the SCBA or during transfill operations.
Also included with the URC Assembly is a pressure relief
valve for protection of the cylinder burst disc.
FIREHAWK M7 CARRIER AND HARNESS ASSEMBLY
DO NOT use this arrier and harness assembly as a
verti al raising or lowering devi e. Failure to follow
this warning an result in serious personal injury or
death.
The carrier consists of a backplate, a cylinder band with
latch to hold the cylinder, and a harness, consisting of
shoulder pads, chest strap (optional), adjustable pull straps,
waist belt, waist belt mounted regulator retainer, swiveling
lumbar pad (optional), and Rescue Belt (optional).
ULTRA ELITE FACEPIECE
The facepiece is available in three sizes (Small, Medium,
and Large).
The facepiece lens is super-hardcoated to meet the
requirements of NFPA 1981.
The facepiece has a low-resistance, pressure-demand
exhalation valve.
An inhalation check valve in the inlet housing keeps mois-
ture and contaminants out of the Firehawk Regulator.
The facepiece has a speaking diaphragm for clear com-
munication.
FIREHAWK M7 HUD
The FireHawk M7 HUD, located on the Ultra Elite
Facepiece allows a user to see cylinder pressure in one
quarter cylinder increments, PASS pre-alarms, battery sta-
tus, and telemetry information (optional) while wearing the
air mask.
FIREHAWK M7 CONTROL MODULE (PASS DEVICE)
The FireHawk M7 Control Module is the user’s interface
with the air mask.
The FireHawk M7 Control Module is equipped with an
analog gauge as well as an LCD to provide the user vital
information: numeric and iconic cylinder pressure, battery
status, thermal alarm (optional), and time remaining.
If the air mask is equipped with the optional FireHawk M7
Telemetry Module, the radio link status and evacuation
alarms are displayed.
The integrated PASS motion sensor is housed within the
FireHawk M7 Control Module.
FIREHAWK M7 POWER MODULE (PASS DEVICE)
The FireHawk M7 Power Module on the lower portion of
the backplate houses the batteries, serves as the cylinder
stop, emits audible PASS alarms, and has buddy lights.

DESCRIPTION
FIREHAWK M7 TELEMETRY MODULE
The FireHawk M7 Telemetry Module provides the firefight-
er with two-way communication with Incident Command.
The firefighter’s vital statistics such as cylinder pressure,
service time remaining, PASS alarm, low battery alarm,
and thermal alarm are transmitted back to Incident
Command. Also, the firefighter has the ability to be evac-
uated remotely by Incident Command. The radio trans-
mitter is located inside of the FireHawk M7 Power
Module.
EXTENDAIRE SYSTEM
The ExtendAire System, located on the user’s left chest,
enables two users to share a common air supply during
emergency escape. The users can couple the Firehawk
Second Stage Regulator from one user to the intermedi-
ate pressure manifold of the other user. Both users will
receive intermediate pressure air from the donor's first
stage regulator and cylinder. The duration of the remaining
air supply will be reduced by at least half.
The SCBA is approved by NIOSH without inter-connecting
two users to one apparatus. NIOSH does not certify
“buddy breathers”. Therefore, the attachment of the
receiver's regulator to the donor's apparatus voids the
NIOSH approval for both air masks.
RESCUE BELT
The MSA Fire Service Rescue Belt is a personal escape
system integrated into an FireHawk M7 Carrier and
Harness Assembly. The system is designed to provide the
user a means of escape from an elevated position. Use of
the Rescue Belt must be in accordance with the user’s fire
department procedures. Care and use instructions are
provided under a separate manual, P/N 10052748.

mask from service and replace the relief valve.
e. Reattach Audi-Larm Alarm to the cylinder valve.
7. High Pressure Hose
a. Inspect the high pressure hose between the Audi-
Larm Alarm and the PR14 First Stage Regulator.
Look for cuts or severe abrasions. If damage is pre-
sent, replace the hose.
8. Cylinder and Valve Assembly
a. Air mask cylinders should be recharged as soon as
possible after use. Cylinders should not be stored
partially charged for two reasons:
If used without recharge, the service life of the air
mask is reduced.
The cylinder burst disc vents excess pressure if a
full cylinder is over exposed to fire or heat. If the
cylinder is not full, it may be damaged before the
burst disc vents.
b. If the cylinder is less than FULL (within 10% of
rated service pressure), recharge it before storage.
Cylinder air must be at least CGA Quality
Verification Level (Grade) D respirable air. In fire ser-
vice applications, MSA recommends breathing air
quality in accordance with NFPA 1989.
c. Inspect the cylinder valve for signs of damage. The
valve may be opened slightly to ensure it operates
properly. Be sure to fully close the valve.
d. Inspect the cylinder body for cracks, dents, weak-
ened areas, corrosive agents causing the fibers to
break or peel, or signs of heat-related damage. If
the cylinder is damaged return it to an MSA Service
Center.
e. Check the hydrostatic test date on the cylinder
approval sticker located on the cylinder neck.
Fiberglass composite cylinders must be tested
every three years. Carbon-wrapped and steel cylin-
ders must be tested every five years.
f. Ensure the needle and gauge face on the cylinder
valve gauge are clearly visible and that the gauge
stem is not bent.
It is also essential that the required inspections and tests
be performed on all air mask cylinders in accordance with
Department of Transportation (DOT) regulations. DOT reg-
ulations require that composite cylinders be retired from
service after the fifteenth year. This does not include cylin-
der valve assemblies that may be reused. Steel and alu-
minum cylinder service life is indefinite if proper inspec-
tion and hydrostatic test procedures are followed and they
indicate that the cylinder may remain in service. Contact
an MSA distributor or sales associate for more information
regarding this policy.
Note: ANSI Z88.5 recommends checking cylinder pres-
sure weekly. For maximum safety the cylinders should be
stored full or empty (pressure above ambient but less than
100 psi).
9. FireHawk M7 Carrier and Harness
a. Operate the latch wing on the cylinder band to
ensure that it opens and closes properly and that it
holds the cylinder securely. If the cylinder band and
latch is locked, the latch wing should not turn.
b. Inspect the back plate for cracks, weakened areas,
or signs of damage due to heat or chemical related
damage.
c. Inspect all harness components for cuts, tears,
abrasions, or signs of damage due to heat or chem-
ical related damage.
10. FireHawk M7 Control Module
a. Inspect the gauge hose and power cable for any
visible signs of damage.
b. Inspect for external cracks in the housing and
ensure the rubber cover is not damaged.
c. Ensure the buttons are not damaged or missing.
d. Ensure the gauge hose and power cable are
securely attached to the FireHawk M7 Control
Module.
11. FireHawk M7 Power Module
a. Inspect the FireHawk M7 Power Module housing for
external cracks and ensure that the FireHawk M7
Power Module, battery tube, and cylinder stop are
securely attached to the backplate.

FIREHAWK M7 HUD
FIREHAWK M7 HUD FUNCTIONALITY
1. The FireHawk M7 HUD allows the user to see the
cylinder pressure while wearing the air mask. The
FireHawk M7 Control Module wirelessly transmits a
signal to the FireHawk M7 HUD (on the facepiece)
while the air mask is in use. The FireHawk M7 HUD
displays the cylinder pressure in one quarter cylinder
increments, by an LED pattern.
As each quarter cylinder pressure has been
reached, a unique LED pattern will be displayed for
approximately 20 second before extinguishing. The
display can be refreshed by pressing and holding
the mode button (green) on the FireHawk M7
Control Module for approximately three seconds.
When 25% of the rated service pressure has been
reached, a single flashing red LED will be displayed
and will continue to flash until the unit is turned off
or the cylinder has be refilled.
The FireHawk M7 HUD must be within approximate-
ly 18 inches of the FireHawk M7 Control Module to
properly receive the signal being transmitted.
2. The FireHawk M7 HUD has a buddy light that flashes

service pressure. This buddy light is not visible to the
user while the air mask is in use.
3. When the user of the air mask remains motionless for
approximately 20 seconds, the PASS pre-alarm will
begin to sound. During this pre-alarm, the FireHawk
M7 HUD will display an orange LED, and this LED will
extinguish when full PASS alarm has been reached or
the pre-alarm has been reset.
4. When an evacuation command has been sent to the
user (if the optional FireHawk M7 Telemetry Module is
in use), the FireHawk M7 HUD will display an alternat-
ing red and orange LED until the evacuation has been
confirmed.
5. The FireHawk M7 HUD has a photo sensor that auto-
matically adjusts the brightness of the LEDs based on
the intensity of the ambient light measured outside of
the facepiece.
6. The FireHawk M7 HUD indicates a low battery condi-
tion by a single flashing yellow LED. When the
FireHawk M7 Power Module reaches a low battery
condition, a double flash of the yellow LED will be dis-
played in the FireHawk M7 HUD. If both the FireHawk
M7 HUD and FireHawk M7 Power Module have
reached a low battery condition, the FireHawk M7
HUD will display an alternating single and double flash
of the yellow LED. If this condition exists, return to

buttons.
o The RESET/OFF button (yellow) on the side of the
FireHawk M7 Control Module resets the PASS
device from the full alarm mode. It also shuts the
unit off after the cylinder valve has been closed and
all pressure is bled from the system. When the
optional FireHawk M7 Telemetry Module is used,
the Reset button allows the user to confirm an
evacuation command.
o The center lighted ALARM button (green/red) acti-
vates the full PASS alarm with or without air pres-
sure.
o The top MODE button (green) will refresh the dis-
play in the FireHawk M7 HUD, activate the backlight
on the display of the FireHawk M7 Control Module,
set the FireHawk M7 HUD to continuous display
mode, and toggle the FireHawk M7 Control Module
digital display mode between pressure remaining
and calculated service time remaining. When the
FireHawk M7 Control Module is OFF, the mode but-
ton (green) can be used to scan an ID Tag into the
unit (when optional FireHawk M7 Telemetry Module
is used).
The FireHawk M7 Control Module turns on automati-
cally when the user opens the air mask cylinder valve.
As the system pressure reaches approximately 200
psi, both visible and audible alarms activate automati-
cally, indicating that the unit is functional (audible
alarms are emitted from the FireHawk M7 Power
Module located on the backplate). The unit remains in
monitor mode until the user closes the cylinder valve,
purges the system pressure, and presses the reset
button (yellow) on the side of the FireHawk M7 Control
Module two times within approximately one second.
While the air mask is in use, if the user is motionless
for approximately 20 seconds, the PASS (FireHawk
M7 Control Module and FireHawk M7 Power Module)
enters pre-alarm. During pre-alarm, the FireHawk M7
Power Module sounds 3 progressively louder tones
and the alarm button on the center of the FireHawk
M7 Control Module and buddy lights on the FireHawk

USING THE AIR MASK
M7 Power Module slowly flash red. Also, during the
PASS pre-alarm, an orange LED will be displayed in
the FireHawk M7 HUD. Movement of the FireHawk M7
Control Module cancels the PASS pre-alarm.
If the user remains motionless for 30 seconds (approx-
imately), the PASS enters full alarm. During full PASS
alarm, the FireHawk M7 Power Module repeatedly
sounds two high-pitched tones followed by a buzz.
During full PASS alarm the alarm button on the
FireHawk M7 Control Module and the buddy lights on
the FireHawk M7 Power Module rapidly flash red.
The PASS can be set into full alarm at any time (even
without air pressure) by pressing and holding the
alarm button on the FireHawk M7 Control Module.
The PASS function uses red and green LEDs behind
the alarm button of the FireHawk M7 Control Module
and buddy lights on the FireHawk M7 Power Module
to display its status visually:
oGreen LEDs start to flash when the cylinder valve is
opened and shows that the device is operational.
